[OpenLayers-Users] Authentication Error

[Christian López Espínola]

Hi,

Please note that not all the readers here are familiar with the usual
ASP.NET jargon.

It seems to me that this is an ASP.NET problem with authentication,
not an OL one.
I've seen that you posted here: http://forums.asp.net/t/1257016.aspx
and that's the better place for asking.

I can try to help you, but this should be offlist because it's not
OpenLayers related, and I would require a minimal demo (code) that
shows the problem.
Don't hesitate to contact me offlist.

HTH
